MACHlNE FOR PRINTING ON BOARDS.

SPECIFICATION forming part of Letters Patent No. 359,972, dated March 22, 1887.

Application filed August 13, 1886. Serial No. QlOfiQO. N0 model.)

To aZZ whom, it may concern:

Be it known that we, FRANCIS X. Hoornn and WILLIAM HoLLINeswoR'rn, citizens of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Machines for Printing on Boards, of which the following is a specification.

This invention relates to a printing-machine for printing upon boards with two colors in one continuous operation.

One description of boards which are to be printed by this machine are used for the ends of boxes, such boxes as are employed for packing goods of various kinds, notably canned goods-such as oysters, fruits, &c. Instead of stenciling upon the end of the ready-made box to denote its contents, the board designed for the boxend is printed previous to being made up into the box. here boxes are made up in large numbers for pack ing special articles, this plan is found more economical, besides producing neat-er and betterwork. Another kind of boards which may U be printed to advantage are those used for advertising-signs.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the machine. Fig. 2 shows two views of the cylinder adjustment. Fig. 3 is a section, on a somewhat smaller scale, showing the upper works sup ported on the upright impression -screws. Fig. 4 is a vertical longitudinal section of the machine. Fig. 5 is a plan view of the upper feed mechanism and side guides. Fig. 6 is a top plan of the machine.

The letterAdesignates the frame and table; 33, the drive-pulley. This machine has two type-cylinders, O 0, both mounted in a movable frame, I), above the table. Each cylinder is designed to work a different-colored ink, so that a board, a, passing below the cylinders, will receive an imprint of two colors. Two ink-receptacles, b b, are provided above the cylinders, and two sets of ink-distributing rollers, o c, of suitable or well-known construction in printing-machines, are also provided. The cylinders and inking mechanisms are mounted on the movable frame I), which is supported on four upright screws, at, each of which has its lower end fitted to turn in aboxbearing, 6, (see Fig. 3,) on the main frame A, and each screw has a fixed collar, f, which is seated on the said frame A. These collars sustain the screws, which, as stated, may turn in the bearing (2. Below the bearing 6 each screw has a spiral spring, g, and a nut, gr.

By this construction the screws are immovturn, and in this way the said movable frame D and all the upper works on it may beraised or lowered to adjust the type-cylinders G O to suit the thickness of the boards, a, which are to be printed. It will thus be seen that while the entire upper works maybe raised or lowered by turning the hand-wheel d the said upper works, after being adjusted, may also, by virtue of the springs 9, yield somewhat in an upward direction to allow for ordiuaryvariations in the thickness of the boards.

Each type-cylinder is to have attached to it, by any suitable means, the die 75, which supplies the imprint. Below each cylinder is a supporting-roller, Z, and between these two rollers Zis a fluted roller, 122-, below the surface of the table,which extends across the machine. This fluted roller is part of the feed mechanism, and bears against the lower side of the board a to carry it from the first cylinder, 0, to the second cylinder, 0.

Two feed-rollers, each havin an elastic face, a, bear down on the upper side of the board a, so that the board is between the lower roller, m, and the two upper ones, a. The two upper rollers, a, (see Fig. 5,) are narrow, and each bears on the surface of the board a along one edge. These rollers are made of metalpt, and have a rubber ring, it, around the metal part.

outside bearing, 1), which is fixed on a side guide, g, which latter guides or directs the board a straight from the first cylinder, 0, to the second one, C. The two guides q are parallel, and. are adjustable toward or away.

from each other, and when their adjustment is changed they carry the feed-rollors a with them, so thatthe adjustment of both is changed at one operation. Each guide (1 has a shank, g, at right angles with it, and the said shank part fits and moves in a groove, 1', fixed to the table A. A set-screw, 1-, on each guide-shank retains the guide wherever it may be set.

An adjustable receptacle forthe board a is on top of the 1nachinc-table A. (See Figs. 1, 4, and 6.) This receptacle consists of kneepieces E, one side of which is fitted to slide in a groove on the table-top, and the other side stands upright. The boards a, preparatory to going under the cylinder 0, are placed or piled up in this receptacle. The bottom board of the pile is the one fed under the cylinder, and the feed mecha-nism to effect this may be termed the primary feed, and consists of a pusher-block, F, fitted in a longitudinal slot, F, in the table-top. This pusher-block is connected with a horizontal rod, G, which is also attached to a second block, G. At the bottom of the frame is a rock-shaft, F, carrying an upright arm, H, the upper end of which is connected with the second block, G, by a linkrod, I. It will thus be seen that the rocking of the shaft]? will impart a reciprocating movement to the pusher-block F, and every time this latter moves toward the cylinders O G the bottom board in the receptacle will be forced under the first roller.

The rock-shaft F" has on one .end a second arm, J, and a crank, L, is on a shaft, L, while a rod, N, connects the said arm J with the crank. This mechanism gives motion to the primary feed. It is necessary to be able to adjust this mechanism so that the pusher-block F mayhave a movement suited to the particular size of the board to be printed. To this end the crank L is made adjustable on its shaft. The cranlrarm has a split-collar part, 8, and a screw, .9, therein serves to permit of the crank-arm being turned on the shaftand set thereon at any point desired. This adjustment serves the purpose last above indicated.

The two cylinders are geared to run in unison; but it is important to be able to adjust them with respect to each other after the printing-dies it have been attached, in order that the two colors may be properly imprinted or registered on the surface of the board a- This is effected by'the devices seen in Figs. 1 and 2. The shaft t of the second cylinder, 0', has a gear-wheel, a, by which it is turned; This gear-wheel turns loosely on the said shaft. Ahead, 1*, is keyed fast tothe said shaft t and is close to the gear-wheeler. Several. clamp plates, 10, are loosely attached to the gear-wheel a, each one by means of a screwbolt, av. The gear-wheeler is atone side of the head 1 and the several clamp-plates w are at the other side. In other words, the rim of the head 11 is betweenthe gear-wheel a and the clamp-plates 20. By turning the screwbolts 00 the loose clampplates w are made to bind or grip the rim of the head a, and thereby the loose-turning gear-wheel it becomes fixed. It will be seen it issimply necessary to loosen the clamp-plates 20, then set eachofl the two cylinders to its proper position, and finally tighten the screw-bolts 0:.
